what fluids did uou to replace or did you use the oem fluids

OEM Fluids , i have not been particularly bothered to try aftermarket alternatives as currently i find OEM to be very cheap , front diff only needs 450ml of liquid and the rear only 500ml. so per change for both you would use pretty much 1 liter container (1000ml) which for me is only $47.50 AUD , for something you should change every 3 track days or realistically every 15-20k depending how hard you push your car its really cheap.


As the old saying goes , Fluids are cheap , Mechanical parts when they break ...are not.





Here is the original diff oil thread
For Convenience Pack cars (the bulk of the GRY sold here in Australia , without LSD) we use the API GL5 75w-85 Gear Oil (LT) both Front and Rear diff.

The Circuit Pack GRYs (primarily sold in UK , with LSD ) use the 75w-85 Gear Oil (LX) for both Front and Rear diff.

Why would you put a Dual-Clutch Transmission Fluid (DCT) into your Manual Transmission gearbox @Sc0oby? , i think i remember using that oil on my Ford Focus RS even though it was a manual but that was specifically because it required the "WSS-M2C200-D2" specification ..i haven't looked but i am pretty sure Toyota would not warrant it unless i am mistaken?

Also putting slightly thicker in the Transfer and Rear , going from 75w-85 to 75w-90 isn't going to make a noticeable improvement on the protection front and you would also possibly be increasing drive train losses with the thicker oil which will shoot-up fuel consumption.

Few members on this forum have taught myself that bigger isn't always better and that there is specific reasons why OEM fluids are specifically fit for purpose.

motul multi dctf is 75w gear oil n wish we could get those oem oil at reasonable prices but eealer locally have been selling them for about same price as thos branded oil like redline or motul

Contacted my local Toyota dealer the other day to book my 2 year service. Was told that it didn't need doing because the sevice interval was every 12K miles or 2 years whichever comes first!!! When I informed them it was actually every 12 months or 6K miles I was met with silence. Fortunately I have another Toyota dealer fairly close by so shall be contacting them to see if they are any better informed.

Mine just had the 3yr/ 60000km done at 1750km..... and it needs to go in every 6mths here in Australia. There's no optional 6mth service, it has to be done here. (They do the engine oil and filter each service.)
